The Parsec parser combinator library described in this paper, utilizes a novel implementation technique for space and time efficient parser combinators that in case of a parse error, report both the position of the error as well as all grammar productions that would have been legal at that point in the input.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Despite the long list of publications on parser combinators, there does not yet exist a monadic parser combinator library that is applicable in real world situations.
